On the heels of the History channel special that explored what Earth might be like if the human race were suddenly to disappear comes a series that provides, in even-more detail, a picture of a post-human future, revealing the fate of structures like the Sears Tower and the Sistine Chapel and creatures that might inherit the places we once lived. Supporting the visuals and special effects are interviews with specialists from the fields of engineering, botany, biology, geology and archaeology.
